Flex SDK Coding Standards & Best Practices
I think this subject probably gets asked a lot by most new Flex programmers. Unfortunately, most of the companies I have worked for did little to enforce or even develop coding standards. Larger companies typically make it a priority to develop standards simply due to the number of incoming and outgoing contractors hired for specific projects. Lack of standards can cause code nightmares later on and virtually no project maintainability.
A good starting point for standards can be from Adobe themselves, who have come up with a nice document detailing basic Flex coding conventions and best practices. See for yourself!
